Brief Summary:
This study is designed to evaluate the short-term and long-term results after three-port laparoscopic surgery for colorectal cancer(TLSC) compared with conventional laparoscopic surgery for colorectal cancer(CLSC).

Condition or disease Intervention/treatment Phase
Colorectal Cancer Procedure: Three-port Laparoscopic Surgery Procedure: Conventional Laparoscopic Surgery Not Applicable

Detailed Description:
At present,surgical treatments is the main means to cure colorectal cancer(CRC).The use of four or more ports has been routine in most laparoscopic colorectal resections. However,the drawbacks are the need for added manpower, consisting of another assistant to provide counter-traction, as well as costs and the unaesthetic effects of additional ports. In order to minimize surgical trauma, improve cosmesis ,reduce manpower,single-incision laparoscopic surgery (SILS) is attracting increasing attention. But it is challenging and highly demanding techniques. Becoming proficient at three-port laparoscopic surgery can make the transition to SILS more nature.Few studies about three-port laparoscopic surgery for colorectal cancer(TLSC) have been reported currently.More studies, especially large-scale, randomized controlled trials are needed to establish the best indications for TLSC. This is a single-center, open-label, non-inferiority, randomized controlled trial. A total of 282 eligible patients will be randomly assigned to TLSC group and CLSC group at a 1:1 ratio. It will provide valuable clinical evidence for the objective assessment of the the feasibility, safety, and potential benefits of TLSC compared with CLSC.

Arm Intervention/treatment
Experimental: Three-port Laparoscopic Surgery
Patients with colorectal cancer undergo three-port laparoscopic surgery.
Procedure: Three-port Laparoscopic Surgery
Patients undergo three-port laparoscopic surgery. The surgery will be completed by a surgeon and a camera-person without another assistant. The surgeon will adjust surgical position to expose the operative field with the help of gravity. All the orther operative procedures are the same as conventional laparoscopic surgery.

Experimental: Conventional Laparoscopic Surgery
Patients with colorectal cancer undergo conventional laparoscopic surgery(4 or more ports).
Procedure: Conventional Laparoscopic Surgery
Patients undergo conventional laparoscopic surgery(4 or more ports).The surgery will be routinely completed by a surgeon,a camera-person and another assistant to provide counter-traction.

Primary Outcome Measures :
  1. Early morbidity rate [ Time Frame: 30 days after surgery ]
    morbidity rate 30 days after surgery

Secondary Outcome Measures :
  1. Operative time [ Time Frame: intraoperative ]
    Operative time(minutes)

  2. Intraoperative blood loss [ Time Frame: intraoperative ]
    Estimated blood loss(milliliters,ml)

  3. Lymph node detection [ Time Frame: 14 days after surgery ]
    Lymph nodes harvested(numbers)

  4. Proximal resection margin [ Time Frame: 14 days after surgery ]
    Length of proximal margin (centimeters,cm)

  5. Distal resection margin [ Time Frame: 14 days after surgery ]
    Length of distal margin (centimeters,cm)

  6. Length of stay [ Time Frame: 1-14 days after surgery ]
    Duration of hospital stay(days after surgery)

  7. Postoperative recovery course [ Time Frame: 1-14 days after surgery ]
    Time to first ambulation, flatus, liquid diet and soft diet (hours after surgery)

  8. Pain score [ Time Frame: 1-3 days after surgery ]
    Postoperative pain is recorded using the visual analog scale (VAS) pain score (0-10 points)tool on postoperative day 1, 2, 3 and the day of discharge

  9. 3-year disease free survival rate [ Time Frame: 36 months after surgery ]
    3-year disease free survival rate

  10. 5-year overall survival rate [ Time Frame: 60 months after surgery ]
    5-year overall survival rate
